- In the ages of victory, as often as the senate decreed some distant conquest, the consul denounced hostilities, by unbarring, in solemn pomp, the gates of the temple of Janus. Domestic war now rendered the admonition superfluous, and the ceremony was superseded by the establishment of a new religion. But the brazen temple of Janus was left standing in the forum; of a size sufficient only to contain the statue of the god, five cubits in height, of a human form, but with two faces, directed to the east and west.
- 1797, Titus Livius [Livy]; George Baker, transl., The History of Rome, [...] In Six Volumes, volume I, London: Printed for A[ndrew] Strahan, and T[homas] Cadell Jun. and W. Davies (successor to Mr. Cadell) in the Strand, OCLC 314578224, book I, page 35:

- "I'll tell you what we can do," cried her persevering patroness; "we can go as masks, and Lady Juliana shall know nothing about it. That will save the scandal of an open revolt or a tiresome dispute. Half the company will be masked; so, if you keep your own secret, nobody will find it out. Come, what characters shall we choose?" / "That of Janus, I think, would be the most suitable for me," said Mary.
- 1879 February 27, A[lexander] M[artin] Sullivan, “On the Zulu War” (speech before the House of Commons of the United Kingdom); quoted in William Jennings Bryan, editor, Irish Orations (The World's Famous Orations), volume VI, New York, N.Y.: Funk & Wagnalls, 1906, OCLC 23127203, and republished on Bartleby.com, 2002, archived from the original on 4 October 2015:

- Janus, with his two heads, his mystery, his depiction as both laughing and serious, and the obvious parallel this forms with the masks of attic tragedy and comedy would make him a double of the two-headed man, the conjurer, and an associate of the trickster in folk comedy as well.

- Good reviews look both backward and forward; an argument could even be made that one must look backward in order to discern the way forward, that backward and forward are two sides of the same research coin. Nowhere is such a Janus-like perspective more apparent than in the current set of reviews.

- But other categories of word-play have not been researched extensively or systematically. Among the latter is the type of word-play known as polysemous parallelism, or more commonly, Janus parallelism.

- 2012, Ruby L. Agnir, “Janus”, in Upward beyond the Brim: Transcending the Limits: Selected Writings, [Bloomington, Ind.]: Xlibris, →ISBN:
- The ability to look at both sides of a coin before giving a verdict can be both a curse and a blessing. […] This "Janus effect" (my term) is a curse when it blocks a time sensitive judgment response, or a decision waiting to be made before long. […] Friendships, sibling harmony, good relationship with associates at work, and especially marriages, could be great and positive recipients of the good that such a Janus effect could bring on.

- 1943, Edmund Vincent Cowdry, Microscopic Technique in Biology and Medicine, Philadelphia, Pa.; Baltimore, Md.: Lippincott Williams & Wilkins, OCLC 615034302, page 102, column 1:

- 1990, László Módis, “Topo-optical Reactions Used in Polarization Microscopic Ultrastructure Research”, in Organization of the Extracellular Matrix: A Polarization Microscopic Approach, Boca Raton, Fla.: CRC Press, →ISBN, page 40:
- The significance of the molecular shape of the dyes in induction of the birefringence of polyanions is illustrated with topo-optical reactions of the Janus dyes. Janus red, yellow, green, black, and blue are cationic azo dyes […]. All of these exhibit a moderate metachromatic effect with sulfated GAGs [glycosaminoglycans].

- In 1900, L[eonor] Michaelis (who later became famous for his studies of enzyme kinetics) found that mitochondria in living cells could be specifically stained by the dye Janus Green B […].

Epimetheus and Janus circle the Lord of the Rings at a distance of just over 151,000 km, about half the distance from Earth to the Moon. Both are irregularly shaped. Janus is 179 km across, while Epimetheus is about 116 km in diameter.

Usage notes
The doors of the temple of Janus were traditionally open only during time of war, and closed to mark the end of the conflict. Thus, the temple of Janus may be used metaphorically to mean conflict or wartime (see the 1879 quotation above).
